Nebula & Light Polution Filters

The Lumicon Deep-Sky Filter is THE foremost broadband filter efficiently blocking ALL mercury-vapor and high & low pressure sodium-vapor lamp light, neon lights and airglow, while allowing the rest of the visible spectrum through.

The Original Lumicon Ultra-High Contrast narrow bandpass filter (24nm) isolates just the two doubly-ionized oxygen lines (496 and 501nm lines) and H-Beta line (486nm) emitted by emission and planetary nebulae, while blocking the rest of the overall spectrum of light.

The renowned, original Lumicon OIII narrow bandpass filter (11nm) isolates just the two doubly-ionized oxygen lines (496 and 501nm lines) emitted by planetary and emission nebulae, while blocking the rest of the overall spectrum of light.

The Lumicon H-Beta Filter isolates only the Hydrogen-beta line of the spectrum (486.5nm) while blocking, completely, the rest of the overall spectrum of light.
